so my car is stock...just curious if i run the 3 inch ZZP pulley, and the NGK one step colder plugs....whats the purpose of running the plugs? is it safer? can it hurt the car in anyway? should i just keep the stock plugs? i need some advice from someone on here like zinner or jmc who knows what they are talking about. thanks guys!

i need my car as a daily driver, and i want it to last..only reason i am considering a pulley is for the hell of it...and its not that big of a mod.

 

Stock plugs are fine with a 3" pulley, unless you record some Knock retard.

 

Come on man, you don't have to call the guy names.

 

im running the zzp 2.8 pulley with ngk 1 step colder plugs and im running fine on 93oct gas...

 

Whats your AFR?? I bet it is higher than 14.0 w/o injectors. Be careful
